What lenders look for when you apply for a mortgage

Mortgage lenders check three things: your credit score, your payment history, and the amount of debt you already carry. A higher credit score usually means lower interest rates, which saves you thousands of dollars over the life of the loan. Most lenders want to see a score of at least 620, though scores above 740 unlock better terms.

Lenders also pull your full credit report to see whether you have missed payments, collections accounts, or judgments against you. They look at how long ago these happened — a missed payment from five years ago matters less than one from six months ago. They calculate your debt-to-income ratio by adding up all your monthly debt payments (car loans, credit cards, student loans) and dividing by your gross monthly income. Most lenders want this ratio below 43 percent.

The timeline matters. If you have recent negative marks, you may need to wait before applying. A bankruptcy typically stays on your report for seven to ten years, but its impact on your score weakens over time. Late payments stop affecting your score after seven years. Collections accounts can be removed sooner if you pay them off, though the account itself remains on your report.

Key Takeaways

  • Lenders use your credit score, payment history, and debt-to-income ratio to decide whether to lend and at what interest rate.
  • Paying down existing debt reduces your debt-to-income ratio and often raises your credit score at the same time.
  • Disputing errors on your credit report through the credit bureau can remove inaccurate negative marks within 30 to 45 days.
  • Becoming an authorized user on someone else's account with good payment history can raise your score, though this works only if the account holder reports authorized users to the credit bureaus.
  • Waiting six months to a year after major negative events (late payments, collections) before applying for a mortgage gives your score time to recover.

Paying down debt to lower your debt-to-income ratio

Your debt-to-income ratio is often the hardest barrier to clear. If you earn $5,000 a month and owe $2,200 in monthly debt payments, your ratio is 44 percent — above the 43 percent threshold most lenders use. Paying down debt directly fixes this problem.

Start with high-interest debt first, usually credit cards. Paying $500 toward a credit card with 22 percent interest saves you more money than paying $500 toward a car loan at 5 percent. As you pay down balances, your credit score often rises because credit bureaus track your credit utilization — the percentage of your available credit you are using. If you have a $5,000 credit limit and owe $4,500, your utilization is 90 percent. Paying it down to $1,500 drops utilization to 30 percent, which typically raises your score by 20 to 50 points.

Do not close paid-off accounts. Closing an account removes available credit from your utilization calculation and can lower your score. Keep the account open and use it occasionally to show activity.

Disputing errors on your credit report

Your credit report may contain mistakes — accounts that are not yours, late payments that were actually on time, or balances that are wrong. You can dispute these errors directly with the credit bureau that reported them. The three major bureaus are Equifax, Experian, and TransUnion. You can request a free copy of your report from each one at annualcreditreport.com, which is the only site authorized by the Federal Trade Commission to provide free reports.

When you find an error, send a written dispute to the bureau. Include a copy of the report page showing the error, a clear description of what is wrong, and any documentation you have (a bank statement, a letter from the creditor, a court record). The bureau must investigate within 30 days and remove the item if it cannot verify it. If the error is removed, your score may rise immediately.

If a creditor disputes your claim and the bureau sides with them, you can add a statement to your report explaining your side. This statement does not change your score, but it appears when lenders review your full report and may help during the mortgage application.

Building payment history over time

Payment history makes up 35 percent of your credit score — the largest single factor. If you have missed payments, the damage fades as time passes and you build a record of on-time payments. Each month you pay on time adds to your history and weakens the impact of past mistakes.

If you have no credit history at all, you can build one by becoming an authorized user on someone else's account. Ask a family member or friend with good credit to add you to one of their credit cards or loans. When they make on-time payments, those payments appear on your report too. This works only if the creditor reports authorized users to the credit bureaus — most credit card companies do, but some do not. Ask before you agree to be added.

Another option is a secured credit card, which requires a cash deposit (usually $200 to $2,500) that becomes your credit limit. You use the card like a regular card, and the issuer reports your payments to the credit bureaus. After six to twelve months of on-time payments, many issuers convert the account to a regular card and return your deposit.

Timing your mortgage application after negative events

The age of negative marks matters. A late payment from two years ago affects your score less than one from two months ago. If you have recent late payments or collections, waiting before you apply for a mortgage gives your score time to recover.

A bankruptcy typically requires a waiting period before you can get a mortgage. Federal Housing Administration (FHA) loans usually require two years after a Chapter 7 bankruptcy discharge or one year after a Chapter 13 bankruptcy begins (if you are current on payments). Conventional loans often require three to seven years. These timelines are set by the loan program, not by your credit score alone.

If you have a collections account, paying it off does not remove it from your report, but it stops growing and may improve your score. Some lenders view a paid collection more favorably than an unpaid one. Ask your lender whether paying off a collection before you apply would help your case.

Checking your credit score and monitoring for fraud

You can check your credit score through your bank, credit card issuer, or free services like Credit Karma and Credit Sesame. These services show you a score and a breakdown of what is affecting it. The score they show may differ slightly from the score a mortgage lender sees, because lenders use specialized mortgage scores, but the difference is usually small.

Monitor your report regularly for fraud. If someone opens an account in your name or makes charges on your account without permission, dispute it immediately with the credit bureau and the creditor. Fraud can tank your score and your debt-to-income ratio at the same time. The sooner you catch it, the sooner you can dispute it and limit the damage.

Set up fraud alerts or credit freezes if you are concerned about identity theft. A fraud alert tells creditors to verify your identity before opening new accounts. A credit freeze blocks access to your report entirely, which prevents new accounts from being opened in your name but also prevents you from opening accounts yourself until you temporarily lift the freeze.

Working with a mortgage lender before you apply

Before you formally apply for a mortgage, talk to a lender about your specific situation. Many lenders offer a pre-qualification conversation at no cost, where they review your credit, income, and debt and tell you what interest rate and loan amount you might may have access to for. They can also tell you what would improve your chances — whether paying down a specific debt would help, whether disputing an error would matter, or whether waiting six months would make a real difference.

Different lenders have different standards. One lender might require a 640 credit score while another accepts 620. One might be stricter about recent late payments. Shopping around before you apply means you can target the lender most likely to work with your situation.

Each time you formally apply for a mortgage, the lender pulls your credit report, which creates a hard inquiry. Multiple hard inquiries in a short time (usually within 14 to 45 days, depending on the scoring model) count as a single inquiry for scoring purposes, so you can shop around without major damage. But inquiries do lower your score slightly, so limit applications to a narrow window.

Frequently Asked Questions

How long does it take to raise my credit score enough to buy a house?

It depends on what is dragging your score down. Paying down debt can raise your score by 50 to 100 points in a few months. Disputing errors can raise it faster if the errors are removed. A recent late payment requires waiting — typically six months to a year before the impact weakens enough to may have access to for a mortgage. A bankruptcy requires two to seven years depending on the loan type.

Will paying off a collection account help my credit score?

Paying off a collection stops it from growing and may improve your score slightly, but the account stays on your report for seven years. Some lenders view a paid collection more favorably than an unpaid one, so it can help your mortgage application even if it does not raise your score much. Ask your lender whether paying it off would make a difference before you decide.

Can I get a mortgage with a credit score below 620?

Some lenders work with scores as low as 580, usually through FHA loans, but interest rates are higher and you may need a larger down payment. Most conventional lenders require 620 or higher. If your score is below 620, waiting a few months while you pay down debt and dispute errors is usually cheaper than accepting a higher interest rate.

Does checking my own credit score hurt it?

No. Checking your own credit report or score is a soft inquiry and does not affect your score. Only hard inquiries from lenders and creditors lower your score, and only slightly. You should check your report regularly to catch errors and fraud.

What if I have no credit history at all?

Most lenders require some credit history to may have access to for a mortgage. Building history through a secured credit card or by becoming an authorized user on someone else's account takes six to twelve months. After that, you can apply for a mortgage, though you may face higher interest rates or down payment requirements than someone with a longer history.
